Improvement in weather-strip for doors



UNITED STATES PATENT OEEIoE.. l

IMPROVEMENT IN WEATHER-STRIP FOR DOORS.

Specification forming part of Letters Patent No. 105,615, dated July 19, 1870.

Be it known that we1 FRANKLIN WEITMORE and EDWARD GONKLIN, ofOhannahon, in Will county, and State of Illinois, have invented a new and useful Improvement on a Weather- Strip for Doors; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawing, in which-a Figure l is a perspective View of the saine applied to a door; Fig. 2, a side elevation of the strip, and Fig. San end elevation of the same.

This in vent-ion relates to that class of weatherstrips which are self-adjusting, induced by the opening and closing of the door, the construction and operation of which we will proceed to explain. l

A groove is cut in the bottom of the door B its entire length, the character of which is shown by the dotted lines z z, Fig. 3,-the ends of which are closed by the metal end plates 1' 1^, held by the screws a. This groove is occupied by the flat spring a, wood strip e, and rubber strip c, as particularly shown in Fig. 2. The spring ais held in place at one end by the adjustable screw z' and by hookin g into the eye m at the other. At the center it is attached to the wood strip e by means of the screw o. The rubber strip c has 011e edge tacked to the bottom of the door at o, Fig. 3, and the other edge to the wood strip e at t, same figure.

` The operation of the device is as follows: The adj ustable screwfi strikes against the metal plate a: in the jamb as the door closes, which compresses the spring a endwise and presses the wood strip e down on the sill.

Figs. 2 and 3 represent the strip as it appears pressed down on the sill, and Fig.'1 represents it up in the groove.

The distance it is desired to move the strip up or down is regulated by the adjustable screw fi. The farther out of the nut s it is screwed the farther down it presses the strip e, so as to accommodate the strip to any aperture between the bottom of the door and the sill.

The object of using the rubber strip c in this particular manner is to render the strip perfectly impervious to wind and water.

1n other strips of this class the rubber is not attached to both door and strip; so there is a circulation of air over the strip e, which is entirely prevented by the present mode of nattachment.

In case a circulation of air be,desired, it is only necessary to screw the adjustable screw z' into its head, when it will not strike the plate x on the jamb, and consequently the strip will not be pressed down, and a passage will be open under the door for the air to circulate, and will also prevent the rubber strip c from rubbing on the sill and wearing out while not yin use.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is as follows:

The weather-strip described, consisting of the wood strip e, rubber strip o, iiat spring a, adjustable screw t', and plates r r, arranged, as shown, in the groove e, constructed and operating in the particular manner and for the purpose set forth.
